The investigators propose a randomized controlled trial with five aims: 1. To investigate the engagement potential and effectiveness of a family-centered intervention (MDFT) and Family Motivational Interviewing Intervention (FMII)/group for teens with alcohol-related crises; 2. To explore differential treatment effects with comorbid adolescents; 3. To examine the role of motivation and family factors as treatment mediators; 4. To examine long-term abstinence, patterns and predictors of relapse up to 18 months follow-up; and 5. To compare the total and net monetary benefits to society of MDFT, FMII/group, and standard care.
